실험 절차

4,7-Dibromo-5-fluoro-benzo[1,2,5]thiadiazole (0.82 g, 2.63 mmol), (4-dodecyl-thiophen-2-yl)-trimethyl-stannane (2.72 g, 6.57 mmol), and Pd(PPh3)4 (50 mg) were combined into a 100-mL Schlenk flask. The system was vacuumed and backfilled with argon for three cycles before 50 mL of anhydrous toluene was added. The mixture was heated at 105° C. for 3 days. After the reaction was cooled down, the solvent was removed by rotary evaporation. The product was further purified by silica gel column with dichloromethane/hexane (v/v, 1/4) as the eluent. Removal of the solvent offered the final product (0.81 g, 47.0% yield) as a red powder after being dried in vacuo. 1H NMR (CDCl3, 500 MHz): δ 8.03 (d, 1H, J=1.0 Hz), δ 7.92 (d, 1H, J=1.0 Hz), δ 7.67 (d, 1H, J=15.0 Hz), δ 7.08 (d, 1H, J=1.0 Hz), δ 7.02 (d, 1H, J=1.0 Hz), δ 2.63 (m, 4H), δ 1.63 (m, 4H), δ 1.26 (m, 18H), δ 0.81 (t, 6H, 7.0 Hz).
